利用海底地形辅助导航是水下载体导航技术致力研究的新方向。该文利用多波束测深系统测量真实地形数据，在此实测地形图的基础上，采用ICCp算法为对准匹配算法，得到水下载体的最佳匹配位置，提高水下载体的导航精度。并利用仿真以平台式惯导系统为例，用卡尔曼滤波对惯导系统误差进行最优估计，取得了较好的效果。
利用海底地形輔助導航是水下載體導航技術緻力研究的新方嚮。該文利用多波束測深繫統測量真實地形數據，在此實測地形圖的基礎上，採用ICCp算法為對準匹配算法，得到水下載體的最佳匹配位置，提高水下載體的導航精度。併利用倣真以平檯式慣導繫統為例，用卡爾曼濾波對慣導繫統誤差進行最優估計，取得瞭較好的效果。

Terrain matching assistant navigation is a new method in navigation technology of the underwater vehicles. In this paper, the real terrain data are measured by multi-beam sounding system, and ICCP algorithm is selected as a registration matching algorithm. Based on the measured terrain data and the algorithm, the accumulative errors of the Inertial Navigation System can be corrected and the optimal marc hing position can be gotten. The platform inertial errors are estimate with the kalman filter in INS. From the simulation results, the inertial errors can be estimated accurately with the matching position differences.
